Updating vCenter fails with the below error:

The value for resume-count in the config table in DB gets updated with the string "resume-threshold" instead of an integer value.
Currently there is no resolution.
Workaround:
To workaround the issue:
Try to unstage and retry stage-install.
1. Log in to your vCenter Appliance via SSH.
2. Run following command: software-packages unstage
3.Start the update process again.
Note: If the default shell was changed to /bin/bash, you can use /bin/appliancesh to enter the Appliance-Shell.
Note: Please ensure you have a working backup before attempting to update your vCenter Appliance.
